ABSTRACT OF THE DISCLOSURE Apparatus for use in a disc player comprises a loading and unloading mechanism for performing selectively a disc loading operation in which a disc inserted into the disc player through an opening for disc insertion is carried to and loaded on a disc rotating device and a disc unloading operation in which the disc is unloaded from the disc rotating device, returned to the opening, and positioned therein with a portion of the disc protruding through the opening. If the disc is accompanied by a protective disc case engaged in the opening, the portion of the disc pro- truding through the opening is received within the case. If the disc is not accompanied by a disc case, the portion of the disc protruding through the opening is exposed to the outside of the disc player and may collect dirt, become damaged, etc. A discriminator detects the presence or absence of a disc case engaged within the opening, and a drive control is responsive to the discriminator for con- trolling the loading and unloading mechanism to reload the disc a predetermined time after the disc is positioned in the opening if no disc case is engaged within the opening and to allow the disc to remain indefinitely in the opening if a disc case is engaged therein for protection of the disc. -1-
